Answer:
The measure of the angle opposite the leg that is 6 inches long is
45 degrees
Step-by-step explanation:
One leg of a right triangle measures 6 inches and the other two sides are equal to 6.3 inches
So the triangle is Right isosceles triangle.
A right triangle with the two legs (and their corresponding angles) equal. An isosceles right triangle therefore has angles of 45 degrees, 45 degrees, and 90 degrees.
That is
The sum of all the angles in the triangle is 180 degrees
Since it is a right isosceles triangle one angle will be 90 degrees and the sum of other two angles will be 90 degrees and equal
90 Degree = 45 + 45

Step-by-step explanation: 72.1°
The circumference of the circle is given to be = 20
The first thing to do here is to calculate the radius of the circle from the circumference given,
Formula for circumference = 2πr or πd, where d is the diameter.
Make r the subject of the formula by equating it to 20
2πr = 20,
r = 20/2π, π = ²²/₇ or 3.142
r = 10/22/7
= ( 10 x 7 )/22
= 70/22
= 3.18.
Now since the radius is known, we could now calculate the central angle of the arc.
Arc length = 2πr∅°/360°, reducing this to lowest term now becomes
= πr∅°/180°
Therefore equate the formula to 4 and solve for ∅°, since the arc length is 4
πr∅°/180° = 4
Multiply through by 180°
πr∅° = 4 x 180°
πr∅°= 720
Divide through by πr to get ∅°
∅° = 720/πr
= 720/3.142 x 3.18
= 720/9.99
= 72.07
= 72.1°
The angle substended by the arc length 4 is 72.1°
Answer:
g(-1) = 5 - 4 = 1
Step-by-step explanation:
Please use " ^ " to denote exponentiation: g(x) = x^3 + 6x^2 + 12x + 8.
Substitute -1 for x in this equation: g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8
Then: g(-1) = -1 + 6 - 12 + 8, or
g(-1) = 5 - 4 = 1
